Once there was a man-eating ogre that lived in a cave near a village it constantly tormented. However, legend has it that just when the village people had given up hope, a mysterious old man wandered in and gave them an axe that instantly split the man-eating ogre in half. The ogrekiller that exists today shares the same folklore.

The Ogrekiller(オーガキラー, Ōgakirā?), also known as Ogre Killer, Ogre, or Giant's Axe, is a recurring weapon in the series. It is usually a mid to high level axe, and sometimes has an added ability of dealing extra damage against Giant-types.
